What kind of subsoils are we talking here? Saturated clays?
I don't know.

CRSI had put out an article stating they had a 10' pile cap with (950) 14" square precast concrete piles.

Water table was at -45' even though basement went to -75, so they had to waterproof the open excavatio. Interesting there are actually two foundations, one for outriggers of upper floors, and one for the remainder. They used 10,000 psi+ concrete too.

There's a lot that can go wrong there.

Just hire one of those Louisiana shoring companies to fix the problem.

This has been a story on the west coast for a while now. The area the building was constructed was a marshy coastal area that was built up with mud dredged from the bay to create more real estate. So the soils suck. On top of that shitty, unstable soil they constructed a concrete frame building, which is much heavier than a steel frame building. I think I read this was the heaviest building ever constructed on the west coast. Then just to make sure it sank, they used friction pilings instead of going to bed rock.

Minus the tragic loss of life, watching that thing go down during 'The Big One' would be awesome. Just think of the gifs that could be made...

Karma will more than pay California back, it keeps getting better with bankruptcy and can't even pay their own people. Cutting their services in half, wages in half, go Jerry Brown

Bet it is those saturated marine clays. Those can be an issue.

Looking at the street view of the MT area, there looks to be plenty of high rise construction going on right beside the Tower.
Must not be too concerned about sinking soils, etc.

If a lawsuit is involved, the owners will be unable to sell their condos while the lawsuit is ongoing. I had a friend in ATL who worked in the court system and owned a condo that was under lawsuit with the builder. She couldn't sell. Somehow she pulled some strings to have the lawsuit somehow "suspended" or the barrier restrictions against selling while under lawsuit temporarily lifted while she did a quick sell. Pays to know people.

My girlfriend used to live on the 55th floor of the tower. She told me the other day she hopes it slides into the Bay with the rest of San Fran..

One of the senior execs in our company lives there. He says everyone suing the builder and anyone even remotely associated with the construction. People can't sell and it's too expensive to tear down and build it again. Bad situation. I believe his apartment costs 5M plus and it's worth zero right now

Can you explain all the construction nearby? By the looks of the google maps street view there are plenty of high rises going up right next to this building. I thought one of the issues was this loose soil.

SF code states a maximum of 2" per year sinkage.

so yes it's up to code.


"downtown" is reclaimed bay marsh.

the whole area will turn to jello if a quake hits it.
there is a fault within the bay itself.
